Joining Multi-line Output with Paste

I was checking the memory on approximately 140 servers using ansible:

but the output appears over several lines e.g.

but what I wanted was the server name and the total memory available. So I first grepped the output to remove the lines I didn’t want e.g.

leaving me with two lines of output per server e.g.

so to combine the two lines for each server into one line:

The ‘paste’ command combines using two hyphens – each representing a line of input. The delimiter between the first line and the second line is a semi-colon and after the second line uses a line break.

Once I had the memory output from each server on a single line with the server name it was easy to sort and format the output.
